3-Methylhexane is a branched hydrocarbon with two enantiomers. [2] It is one of the isomers of heptane . The molecule is chiral , and is one of the two isomers of heptane to have this property, the other being its structural isomer 2,3-dimethylpentane .
C 3 H 5-Cl + NaF → R-F + NaCl This kind of reaction is called Finkelstein reaction . [ 2 ] However, it is also possible, for example, to produce phosphorus fluoride compounds by transhalogenating chlorine, bromine or iodine bound to phosphorus with a metal fluoride.
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
Regiochemistry follows from the reaction mechanism, which exhibits halogen attack on the least-hindered unsaturated carbon. The mechanism for this chain reaction resembles free radical halogenation, in which the peroxide promotes formation of the bromine radical. However, this process is restricted to addition of HBr.
[1]: 625 As given in the example of 3-methylhexane and its higher homologues, branched hydrocarbons can be chiral. [1]: 627 Chiral saturated hydrocarbons constitute the side chains of biomolecules such as chlorophyll and tocopherol. [3] Unsaturated hydrocarbons, which have one or more double or triple bonds between carbon atoms.
For example, C(CH 3) 4 (neopentane) is named 2,2-dimethylpropane. If there are different groups, they are added in alphabetical order, separated by commas or hyphens. The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures.
In organic chemistry, dehalogenation is a set of chemical reactions that involve the cleavage of carbon-halogen bonds; as such, it is the inverse reaction of halogenation. Dehalogenations come in many varieties, including defluorination (removal of fluorine ), dechlorination (removal of chlorine ), debromination (removal of bromine ), and ...
In chemistry, solvolysis is a type of nucleophilic substitution (S N 1/S N 2) or elimination where the nucleophile is a solvent molecule. [1] Characteristic of S N 1 reactions, solvolysis of a chiral reactant affords the racemate.
